The sides of the ladder of the double helix are made of groups of hydrogen bonding between the purines and pyrimidines. The backbone is made up of sugar-phosphate.

What are sides of a double helix made of?

The sides of a double helix are made of repeating units of sugar and phosphate molecules, which make up the backbone of the DNA molecule. These sugar-phosphate backbones are connected by hydrogen bonds between the nitrogenous bases, forming the characteristic twisting structure of the DNA double helix.

The DNA double helix looks like a twisted ladder What makes up each rung of the ladder What makes up the sides of the ladder What holds the rungs together at the sides?

Each rung of the DNA double helix is made up of a pair of nitrogenous bases (adenine-thymine or guanine-cytosine). The sides of the ladder are made up of alternating sugar (deoxyribose) and phosphate molecules. Hydrogen bonds hold the nitrogenous bases of the rungs together, creating the structure of the DNA double helix.

Is the sides of the DNA molecule are made up of repeating nitrogen bases and sugars?

The sides of the DNA molecule are made up of repeating sugar-phosphate groups, not nitrogen bases. The nitrogen bases are arranged in the middle of the DNA molecule and form the rungs of the double helix structure.

Does a polygon have four sides?

Answer: Yes it can have four sides, but as the explanation below shows, it can have many other numbers of sides as well. Explanation: A polygon can have as many sides as needed. We give specific names to polygons dependent upon the number of sides that it has: triangle: A polygon made with three sides. quadrilateral: A polygon made with four sides. pentagon: A polygon made with five sides. hexagon: A polygon made with six sides. heptagon: A polygon made with seven sides. octagon: A polygon made with eight sides . In fact, if we have n sides, we can call that polygon an n-gon. So in short, yes a polygon can have four sides, so all 4 sided shapes are polygons, however, not all polygons have four sides.

What forms the sides of DNA ladder?

The sides of the DNA ladder are formed by alternating sugar and phosphate molecules. These sugar-phosphate backbones run parallel to each other on opposite sides of the double helix structure of the DNA molecule.


What make up both side of DNA double helix ladder?

The two sides of the DNA double helix ladder are made up of nucleotides. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The nitrogenous bases on opposite strands pair together through hydrogen bonding (adenine with thymine, and guanine with cytosine), holding the two sides of the ladder together.
